J/ApJ/659/1176    Study of bars in 180 spiral galaxies         (Marinova+, 2007)

Characterizing bars at z∼0 in the optical and NIR: implications for the evolution of barred disks with redshift. Marinova I., Jogee S. <Astrophys. J., 659, 1176-1197 (2007)> =2007ApJ...659.1176M
ADC_Keywords: Galaxies, optical ; Infrared sources ; Morphology Keywords: galaxies: evolution - galaxies: fundamental parameters - galaxies: kinematics and dynamics - galaxies: structure Abstract: Critical insights on galaxy evolution stem from the study of bars. With the advent of HST surveys that trace bars in the rest-frame optical out to z∼1, it is critical to provide a reference baseline for bars at z∼0 in the optical band. We present results on bars at z∼0 in the optical and NIR based on 180 spirals from OSUBSGS (Eskridge et al., 2002, Cat. J/ApJS/143/73). File Summary:

Note (1): There are 136 moderately inclined galaxies (sample S4) and 33 highly inclined galaxies. Note (2): From the RC3 (de Vaucouleurs et al., 1991, Cat. VII/155). Note (3): Based on visual inspection of optical images and runs as follows: B = strongly barred AB = weakly barred A = unbarred Note (4): Most values are from the NBG (Tully, 1988, Cat. VII/118), which assumes a Hubble constant of 75km/s/Mpc. Exceptions are NGC 6753, NGC 6782, NGC 5078, NGC 6907, NGC 7814, and ESO 142-19, for which distances from RC3 (Cat. VII/155) are used. Note (5): Values are from the NBG, except for NGC 6753, NGC 6782, NGC 5078, NGC 6907, NGC 7814, and ESO 142-19 where RC3 data are used. Note (6): Calculated the (B-V)T color from RC3 (Cat. VII/155). Note (7): From the IRAS Revised Bright Galaxy Sample (Sanders et al., 2003, Cat. J/AJ/126/1607).

Note (1): Calculated from B band ellipse fits before deprojection; Note (2): from ellipse fits after deprojection: u = unbarred b = barred ? = Initially classified as "b", however the bar signature in the radial profiles is marginal. Further inspection has shown that this galaxy should be unbarred. Note (3): Of large-scale bar after deprojection.
